No joke- the Hill Topper kit has changed my life! I cannot believe how fast I can get around. - Kristen (San Francisco)

Throttle or pedal assist? We designed the Discover to have both so you don't have to choose. The PAS (pedal assist system) gives you 5 levels assist to get you where you need to go. And hey, if the legs can't make it up that hill or you need to quickly accelerate through the intersection, the throttle is there to give you a hand.
